The lens can even use it’s mighty-morphing transformer powers to change shape and thus it’s focusing power! Some Cataract Terminology Phakic: When you have your natural lens Psudophakic eye: When a cataract is replaced with an artificial lens Aphakik eye: When a cataract is removed but isn’t replaced.
Lens Anatomy We can’t go any further in our discussion without first describing the anatomy of the lens and how it sits in the eye.
The ciliary muscle can be thought of as a camera diaphragm, or if you prefer a more entertaining description, a sphincter muscle.
When this sphincter contracts, the central “hole” gets smaller causing the zonular “springs” to relax.
Cataract surgery is our signature operation, so it’s worthwhile to familiarize yourself with basic lens anatomy and surgical goals.When conceptualizing the structure of the lens, you may find it useful to think of it like a yummy peanut M&M candy.
